# --production skips devDependencies (vitepress + algolia from docs, typescript, @types)
# --linker=hoisted avoids Bun's default isolated-linker bugs that corrupt
# multi-stage Docker builds: transitive deps not symlinked (oven-sh/bun#23524,
# e.g. @sinclair/typebox via elysia) and a store-population race producing
# EISDIR on freshly-linked packages (oven-sh/bun#29489, e.g. camoufox-js).

# devDeps installed (bun 1.3.x quirk). Prune better-sqlite3 sources + unused impit
# platform binaries inside this stage so the subsequent COPY --from=deps in stage 3
# pulls a smaller layer (Docker layers are unions, not diffs — can't shrink post-COPY).
